Your 90% to a Slayer! Go for that man
I was considering a mini or GS3 but went Slayer. Note OP needs a better grinder (I prefer Kafatek flat max), and needs to confirm appropriate water before worrying more about the machine IMO Otherwise, there's another ~2k in making sure that the water is correct.
I have a Slayer and was going to say Hennessy venom.
You want the best? Straight to the Slayer you go.
Just buy cold brew concentrate- that will be better than what you can get from a crappy machine and has no learning curve Stumptown is solid and has nation distribution (I believe) - you can buy a wand frother if you prefer hot over cold latte, however whole milk and stump town concentrate will get the job done and be better Or buy a kafatek grinder and Slayer espresso machine and stop being a scrub :)
I'm guessing you don't hear more about it because there is a private forum for Decent owners & they spend their time there where the threads are Decent specific & they get help from Decent users rather than people who have heard things about these machines & make comments. I owned a DE1Pro for \~4 years. Initially I loved it. Then I realized that after that initial period I no longer wanted to make changes to recipes & I was just using one or two and most of its capabilities were lost on me. Then I started to hate the sound of it, the mouthfeel was lacking & it just looked ugly compared to traditional machines. The Decent hadn't changed, I had and my needs had changed. Thankfully it's very easy to resell & retains its value. I will say that the best thing about the Decent IMO is the company & CEO that stand behind it. Very good support & service with an affordable warranty that can be renewed as the machine ages.
I don't know. When I got the Slayer I compared it to the Decent and there was an immediate and noticeable difference in mouthfeel shot for shot. I also compared a Slayer profile on the Decent with the Slayer and there was no similarity between the two.
If you're making lattes with dark roast espresso and torani syrups, no I probably couldn't tell the difference. Likewise if you're saying don't include variables the Breville doesn't have, then again no I probably couldn't tell the difference. If you're saying an experienced home barista or professional does their best dialing in a light roast single origin coffee with the same grinder, using all the available features of a Slayer home espresso machine or just a Rocket Appartamento, and we're comparing the 5th try dialing in on each machine, straight espresso... Obviously yes definitely I could taste the difference. If it was me making the coffee you could taste why I paid more for my machine by the 7th at least.
